What does it mean when my Brewtus IV surges during a 25 second shot? It usually happens about 15 seconds in. Plenty of water in the tank. Is it time for a cleaning perhaps?
techkathy Give the machine a vigorous back-flushing if you haven't done so recently. Can you describe the surging in a little more detail? Is the needle on the gauge raising and falling? Is the sound of the pump changing?
